Description

High-Pressure Fiber Optic Feedthroughs (Up to 100 MPa)

Hermetic Sealing for the World’s Most Demanding Environments

Our custom fiber optic feedthroughs are engineered to thrive in high-pressure industrial applications. Utilising advanced glass solder or epoxy sealing, we provide hermetic integration for Single-Mode (SM) and Multi-Mode (MM) fibers across the entire spectrum, from UV to IR wavelengths.

Our feedthroughs are built for longevity, ensuring signal integrity where standard seals fail. We deliver solutions tailored for extreme thermal cycles, chemical exposure, and high-density channel requirements.


Engineering Advantages

  • Ultra-High Pressure Resistance: Certified to withstand pressure differentials up to 100 MPa (14,500+ PSI).

  • Superior Sealing Technology: Choice of glass solder or epoxy sealing for a permanent, leak-proof barrier.

  • Rugged Construction: Bodies manufactured from high-grade stainless steel for maximum corrosion resistance.

  • Custom Body Geometries: Fully compatible with NPT, SAE, and DN standards, or entirely bespoke flange designs.

  • Universal Connectivity: A wide range of connectors and adapters to match your existing infrastructure.


Industry-Specific Solutions

Our high-pressure feedthroughs are the trusted choice for critical missions in:

  • Energy & Resources: Oil and gas exploration, subsea production, and mining.

  • Defence & Aerospace: High-altitude systems and military-grade sensor arrays.

  • Processing & Automation: Chemical processing plants and high-pressure industrial automation.
